MACHINE FOR THE manuraqruan or Mmcaiafoxa g Application filed June 24, 1930, Serial No.

My invention relates to a machine for the manufacture of match-boxes, and more particularly the outer portion of wooden boxes.

The object of my invention is to improve the output of such machines by increasing their speed. 7

The speed of such machines was hitherto limited by the fact that the holder for the strip of wood of which the outer box is con structed had to be taken into account. It is necessary to secure the beginning of the strip to the winding mandrel or winder. A pivotally mounted tongue, the strip holder, was

used for this purpose controlled by a spring mandrels with a simple slot for introducing the beginning of the strip, i. e. without strip holder.

The quick withdrawal of the ejector plates calls for a correspondingly concentrated or steep curve on the circumference of the drum cam and it confined the speed range of the machine to such narrow limits as they were observed hitherto.

According to my invention the ejector plates are after the ejection of a finished box withdrawn at a noticeably slower speed, in fact so slowly that they leave the'path of the new strip then only, when the second side of the box must be pressed against the mandrel. In this way the decisive curveof the cam becomes flattened out to such an extent that the speed of the machine may be increased by about one third and thus also the capacity of the machine by the same amount, This possibility is still further ensured in the new method of operation that in the moment of introducing the fres strip. 111 .0 the.

' in the moment of the insertion of the new strip into the winding mandrel they are still within the range of themagazine. They should give the magazine or the path ofthe strip free then only when the mandrel c has already been turned into the position shown in Fig. 3 of the drawing. In this position the ejector plates should according to my inventionc just have left the path of the strip m w so that during the further rotation of the mandrel c the strip m can be forced against the broad side of the mandrel. During the introduction of the strip m into the slot m of the mandrel the slot is still close'd'at the back, as clearly'visible in Fig. 4; of the drawing. It is thus impossible that a strip should penetrate too far by reason of excessive acceleration even at'the increased speed of the machine. r Figs. 3 and 4 show that the winder c of the new machine can perform a rotation of about 45+60=105 before theejector plates 9 h give the path of the strip m free. This means that with the usual dimensions of the 0;, parts of the machine the stroke curve of the cam can occupy a'portion of the circumference which is about 52 longer than in machines used up to now. This means a stretching or reduction of the gradient of the cam which-permits of an-increase of the speed of the machineand thus its output by approxi-' mately one third.

. I claim as my invention In a match boX machine for forming the outer casings of the boxes from wood strips, the combination of a magazine for the strips and from which the same are ejected, a r0- tary mandrel to receive the ejected strips and form them into casings, reciprocating ejector '4 plates embracing and stripping the casings from the mandrel, and a cam operating to reciprocate said plates timing their advance movement to first control the advancing strips from the front of the magazine and 5 into the mandrel and causing the plate to clear the magazine on their return movement to strip the mandrel during a rotary movement-thereof through an angle of 105 from the pointwhere the succeeding strip is in? 5a serted.

In testimony whereof I affix my signature.
